Attenborough Sand Martin Colony, Thursday 25 May

The first broods of Sand Martins have left their nests at Attenborough so I decided to make the first attempt at catching adults with the new mono-filament net. Phil, Pete S and I set the new and very fragile net in perfectly calm conditions and retired into the hide. We knew we would only be likely catch any number of birds at face’s B and C as face A had been affected by a leaking roof over the winter and there was only one active nest in it. We did have perfectly still conditions but the sun was out fully from the start so to end with a catch of 54 Sand Martins (including 24 recaptures), which is nearly as many as we had in 3 visits last year, suggests the new net is making a difference. Even better, 45 of them were adults including returning adults and pulli from 2016, 1 pullus from 2015 and a bird originally ringed at Redhill Marina in 2014 that was also caught at Attenborough in 2016. The French connection with the colony continued this year with the capture of another French ringed bird. The 9 retrap juveniles were all birds recently fledged from this colony.

Attenborough CES Visit 3 - Sunday 21 May

The third CES visit of the season to Attenborough was carried out on Sunday by Duncan, Gary, Sue, Alex, Jake and I. We were also joined by Trish Horlock. Much better weather than last week meant we could get the nets set immediately. It stayed relatively calm and mostly sunny throughout the morning. However, the better weather did not result in a better catch. It was quiet all morning and we ended with 29 birds (21 new/8 retrap) comprising: Great-spotted Woodpecker 1/0, Blackbird 1/0, Wren 2/1, Dunnock 3/1, Robin 1/0, Blackcap 4/2, Chiffchaff 2/1, Cetti’s Warbler 1/0, Great Tit 1/0, Treecreeper 0/2, Bullfinch 5/1. The oldest retrap was a Dunnock from 2015.

Attenborough CES Visit 2 - Sunday 14 May

The second CES visit of the season was carried out on Sunday by Duncan, Gary, Sue and I. The morning started overcast with rain but we continued down to the site as the rain was forecast to stop. We waited in the rain until 0635 when it did stop and then put up the nets. The skies soon cleared to blue with a light breeze. 
The catch was slower than last week. We ended with 36 captures (22 new/14 retrap) made up of: Magpie 1/0, Blackbird 3/0, Song Thrush 1/0, Dunnock 1/2, Robin 1/2, Blackcap 3/1, Chiffchaff 1/2, Blue Tit 3/1, Great Tit 0/5, Long-tailed Tit 1/0, Treecreeper 1/1, Bullfinch 4/0, Greenfinch 2/0. 
The Greenfinches were only the fifth and sixth ever caught on our CES visits. The oldest retrap was a Dunnock from 2012.

Attenborough CES Visit 1 - Sunday 7 May

The first CES visit of the season was carried out on Sunday by Alex, Duncan, Gary, Jake and I. We were also joined by Nigel Bosworth later. The morning started overcast with a breeze but the clouds started to break and the breeze dropped. The catch was steady throughout the morning and the highlights were a retrap Jay (that was originally ringed on the first CES session last year) and the first juvenile birds of the season: a couple of Robins and a Long-tailed Tit. 
Total catch was (new/retrap) 41/7 made up of: Jay 0/1, Blackbird 1/0, Dunnock 6/1, Wren 2/2, Robin 5/0, Blackcap 4/0, Chiffchaff 4/1, Willow Warbler 2/0, Reed Warbler 1/0, Sedge Warbler 2/0, Blue Tit 1/0, Great Tit 5/1, Long-tailed Tit 1/1, Treecreeper 3/0, Bullfinch 4/0. 
This was a really good start to the CES season, let’s hope it continues in the future visits. The Willow Warblers were the first caught on the CES since 2013 and the Sedge Warblers the first since 2012. The oldest retrap was a Wren from 2015. We also ringed a couple of Tawny Owl chicks in one of the boxes.

Holme Pierrepont, Sunday 23 April

Alex, Sue, Gary and I made the second visit to the Grange end of Holme Pierrepont today. We were joined by Jake Bull who was interested to see some bird ringing. Decent weather, calm with occasional cloudy periods prevailed. Catching started slowly and continued that way all morning. We ended with a total of 23 birds including 11 retraps. The species totals were (new/retrap): Robin 1/3, Wren 1/1, Blackcap 4/0, Reed Warbler 4/0, Cetti’s Warbler 0/1, Willow Warbler 0/3, Dunnock 0/2, Reed Bunting 1/0, Great Tit 0/1, Magpie 1/0. The oldest retrap was a Robin from 2012, the oldest returning warbler retrap was a Willow Warbler from 2014. The main change from last Monday was the return of a few Reed Warblers and Whitethroat that started sing near the base part way through the morning.

Brackenhurst, Sunday 2 April

Last weekend Gary and I took down the feeders at Sutton Bonington after some poor catches, so this morning Duncan, Sue and I headed east and netted the Brackenhurst feeding site. The weather was good with a slight frost showing in Orwin's first thing, but the sun soon melted that. We had a good session that started fairly quietly, second round produced 0 birds but then picked up and just kept going, we were still catching well when we took down to leave. We ended on 53 birds in total including 12 retraps made up of (new/retrap): Wren 1/0, Chiffchaff 4/0, Blackcap 1/0, Blue Tit 0/1, Great Tit 1/0, Goldfinch 1/0, Chaffinch 2/3, Reed Bunting 1/1, Yellowhammer 30/7.

All the warblers, except for one Chiffchaff, were from Orwin's. All the other birds, apart from one Great Tit, were from the feeders. The oldest retrap was a Yellowhammer from 2014.

Brackenhurst Ringing Demonstration, Wednesday 8 March

Jim, Kev, Esther, Erin and myself set out on a relatively mild morning, later accompanied by Lorna and Simon. Again, the feeders had been completely emptied by squirrels a couple of days earlier but had been topped up prior to the ringing demo. As usual, we set up nets at both the ringing site and Orwin’s field. The morning started off at a fairly leisurely pace but we were kept busy all morning with a constant supply of birds and interested students.

We caught 61 birds of 9 species, as follows (new/retrap): Dunnock 2/0, Robin 0/1, Goldcrest 1/1, Blue Tit 1/3, Great Tit 2/2, House Sparrow 2/0, Chaffinch 2/0, Yellowhammer 29/13, Reed Bunting 2/0.

It was a decent catch of Yellowhammers and of note were a couple of that were 6 years old, one of which was first ringed in 2011 as an adult. The two Goldcrests were a male and female together (presumably a pair).

Finally, we were treated to Simon’s award-winning lemon and lime drizzle cake – delicious!

Sutton Bonington, Saturday 4 March

Duncan, Gary and I netted the feeding site this morning. The last couple of visits have produced very few birds despite the hoppers being emptied of seed quickly. We discovered by removing nets and watching the feeders there are plenty of birds coming in but as soon as nets are erected the ‘openness’ of the site makes the nets too visible and puts the birds off. This proved to be the same this morning.

The weather was good but birds caught were few, despite plenty of Yellowhammer and Reed Bunting coming in as soon as the nets were down. Weather permitting the next visit will see whoosh nets being deployed!  We ended with 18 birds including 5 retraps made up of (new/retrap): Song Thrush 1/0, Wren 1/1, Long-tailed Tit 1/0, Goldcrest 1/0, Chaffinch 1/0, Yellowhammer 5/4, Reed Bunting 3/0. The oldest retraps were from last winter.


Heron caught on camera

An Attenborough ringed Grey Heron was recently caught by a camera trap in Northamptonshire. Trap operator, Keith Walkling, said: “I get a bit of an influx of herons at this time of year, when the frogs start to appear, although there is no nesting colony on site. Peak numbers would be 8 - 10 although there always seems to be 1 or 2 about. The nearest colony would probably be at Eyebrook reservoir, about 5 or 6 miles to the north and there is one to the south at Titchmarsh BCN Wildlife Trust Reserve. I keep a couple of trail cameras on site all year round so will let you know if I get it again. Coincidentally our local BCN group had a very interesting talk in November given one of your colleagues, Nigel Slater, and our plan is to visit Attenborough some time soon.”

Brackenhurst Ringing Demo, Monday 13 February

We had a good team out for this event: Jim, Kev, Gary, Louise, Erin, Lorna and I set up at first light in pretty chilly and slightly windy conditions. Quite a few birds were around, although catching was rarely anything more than steady. This suited us though as we also had a steady stream of undergraduate students coming to see what we do and learn a little about ringing. Many were on environmental courses and they were an appreciative audience.

We ringed 28 birds of 6 species, comprising (new/retrap): Dunnock 0/3, Robin 0/2, Blackbird 1/0, Blue Tit 5/3, Great Tit 2/2, Yellowhammer 9/1. The oldest retrap of the morning was a Robin ringed in November 2015.

By about 10 o'clock, the sun came out and the breeze stiffened a little and the capture rate plummeted. There were still good numbers of birds in the general area though, with perhaps 50 or so Yellowhammers hanging about. Over 100 Fieldfare were also moving around the nearby fields, both Green and Great-spotted Woodpeckers were heard (the latter drumming), a few Siskin came over and 2 Woodcock were flushed from marshy grassland on the edge of a copse. Highlight of the morning was probably the flock of 7 Whooper Swans that flew over heading north.

Brackenhurst, Monday 6 February

Jim and myself set out on a very cold morning with Rebecca coming along to watch. Despite the feeders being empty and lots of squirrels hanging around, the morning started off very busily with a good number of birds. Then suddenly things dropped off around 10am, and as we were freezing cold (note the icicles on Jim's Landy!) we packed up.

We caught 41 birds of 7 species as follows (new/retrap): Dunnock 1/2, Robin 2/7, Blackbird 3/0, Blue Tit 2/1, Great Tit 3/5, Chaffinch 1/2, Yellowhammer 8/4.

The oldest retrap was a Robin ringed in January 2013 and we also caught both Blue and Great Tits ringed in November 2014. This was also the last ringing outing for Jim's beloved Landy - it has been on many adventures, and involved in countless scrapes, but we all loved it! Hopefully the new one will be just as useful.

3 Days at Sutton Bonington

Alex, Sue, Gary and I netted the feeding site again this morning. There was a slight frost to start with but it was clear and still, clouding up later. Catching was fairly steady throughout but still no large numbers despite the cold week we had just had and the seed in the hoppers being consumed swiftly. We ended with 31 birds including 16 retraps made up of (new/retrap): Fieldfare 1/0, Blackbird 0/1, Dunnock 0/3, Robin 0/6, Great Tit 1/1, Blue Tit 3/0, Long-tailed Tit 0/1, Goldcrest 1/0, Goldfinch 1/1, Chaffinch 0/1, Yellowhammer 5/1, Reed Bunting 3/1. The oldest retraps were from last winter.

Gary and I, along with Lucy from York netted the copse at the dairy farm site this morning. No frost today but overcast and misty at times. As we walked to the copse first thing we had both Barn and Tawny Owl fly in front of us. Catching started fairly briskly for this small site but dropped off later. We ended with 26 birds processed including 10 retraps made up of (new/retrap): Blackbird 1/0, Wren 1/0, Robin 0/3, Great Tit 1/2, Blue Tit 2/5, Chaffinch 11/0. The oldest retraps were from last autumn. We have generally noticed an increase at all sites over the last couple of years of ‘scaly leg’ in Chaffinch. Today saw it reach a new level, we ringed 11 Chaffinch but had to let 12 go un-ringed because they were suffering from the condition!

Lucy, Duncan, Gary and I netted the sewage treatment plant this morning. The day started with breeze and light rain that had us hanging around for a break so that we could put the nets up. It did stop raining after a while and we eventually put up 4 nets although 3 of them were being caught by the breeze quite a bit. Not long after 1030 it started to rain again, sharply this time and forced us to finish early. Catching was slow but we did manage to catch a couple of Pied Wagtails and get samples from them – a prime target species as they feed directly from the filter beds. A surprise in the net on the last round was a Chiffchaff. We ended with 10 birds including 1 retrap made up of (new/retrap): Pied Wagtail 2/0, Wren 1/0, Long-tailed Tit 5/0, Goldcrest 0/1, Chiffchaff 1/0. The retrap was from the last visit.
